Major Blowouts and Mayor Bonds

I think it's time for some showdowns and real bonds to be made.
Like Chuck/Blair relation was always said to be a bomb ready to go off then i say set it (my idea would be have Dan save her from a life or death something). And some bankrupt would be nice or someone dieing or something. So this is my Blowout is Chuck/Blair and my Bond is Dan/Blair what's yours?
